So far, I've come up empty handed in locating any information online about expansion valve removal for an e36. Since the description in the Bentley is so scant, the fine members of this forum are my last prospect before turning the job over to a "professional."
I did, however, discover a diagram on the Real OEM site. Under the "Heater and Air Conditioning" category, there is the "Heater/Radiator/WDEN Cable" subgrouping. The diagram can be seen at this address:
The part in question is listed as "#3" and is held down by what appears to be two bolts. The first bolt (#15, Fillister head with washer) secures the set of copper pipes against the valve. The second bolt (#5, Threaded bolt), which is the part I can't seem to remove (or locate for that matter), secures the valve to its base.
It's been in the mid-nineties here in central NC with 100% humidity and I've never sweat like this before in my life. Any advice would be a blessing. Thank you!
